Recent-ish changes to the core shrinker have made the code more prone to hit OOM, and worse do so without even touching swap. My hypothesis is that this is a balancing issue between shrinking the VM lists and the slabs, such that writeback of our objects is not performed starving the system of pages. Patch 5/5 introduces manual writeback handling for our shrinker, but afaict it should be unnecessary. Nevertheless, I think it will come in useful.
I am having difficulty in getting results from QA, but so far these have improved mempressure handling on my machines. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
